Cheat sheet: JavaScript Array methods

Deriving a new Array from an existing Array:

['■','●','▲'].slice(1, 3)          ⟼ ['●','▲']
['■','●','■'].filter(x => x==='■') ⟼ ['■','■']
    ['▲','●'].map(x => x+x)        ⟼ ['▲▲','●●']
    ['▲','●'].flatMap(x => [x,x])  ⟼ ['▲','▲','●','●']

ACL / Roles + Permissions

https://github.com/djvirgen/virgen-acl Simple and elegant, create your own checks. No middleware?

https://github.com/OptimalBits/node_acl Use as middleware, create your own roles and access. Great choice.

https://github.com/tschaub/authorized Similar to connect roles... but a bit more robust? you can create roles and action, and associate many roles with that action
